About Buechel Pappas Knee
Based on experience with the LCS, Dr.Buechel and Pappas have refined the design and have came out with B-P™ Total Knee System
Proven Design
The superior engagement of the B-P™ tibial bearing with the femoral component makes the use of a posterior stabilized (PS) device unnecessary. Since PS devices are characterized by highly excessive post against cam stresses, lack of axial rotation, failure in providing full flexion and other problem, such devices are undesirable.
This system, including the revision knee system, contains a wide variety of components allowing optimal treatment of a wide range of pathologies.
An integrated system provides a great number of surgical options. In the event of the need for the revision of a component of an integrated system, the need to remove properly functioning, well fixed, components is eliminated.
Product Details
Femoral Component
- Designed to replace the complex geometry of the femoral articular surface while maintaining an anatomical valgus angle.
- The radii of curvature decrease from anterior to posterior in a coordinated fashion to provide full flexion
- Maintaining excellent bearing congruity with the tibial component.
- Its geometry also congruently accommodates varus-valgus and rotary motions as well as providing congruent contact for the patellar components or the natural patella.
- Improved articulating surface accuracy and fit improve the congruity of the articulating surfaces in the B-P™ component.
- Material : Cobalt Chromium
Mobile Bearing
- Ultra congruent- Deep Dish Design for Low contact stress
- Excellent bearing congruity and superior dislocation resistance is provided.
- These bearings come in a variety of thicknesses to allow flexibility in bone resection of the tibia, to correct gross deformities.
- Material : UHMWPE
Tibial Component
- This plateau is intended for use with the Tibial Bearing.
- Stop-pin mechanism provides ±45° axial rotation which allows normal activity
- Engages only in the event of bearing subluxation.
- Material : Cobalt Chromium
Patellar Component
- Congruently matches the spherical anterior flange segments and sulcus of the femoral component.
- Allows for variations in anatomical position as well as surgical misalignment
- Anatomical tracking of Patella
- Material : UHMWPE
All Poly Tibial Component
- Medial Pivot High flex Design.
- Provides upto 20° axial movement
- This device is superior to other competitive products in use with regard to providing lower contact stresses.
- Material : UHMWPE
